Recommended Posts

Posted

When double-click 'C' or 'D' drive in "My Computer", it goes to the link

http://www.nhanhlen.com/ intead of showing the content of the drive.

Could it be the workstation infected by virus? Symantec antivirus did not

detect virus after performed a full scan.

This can be an adware, which is represented as BHO (Browser Helper Object)

which hooks DocumentComplete & BeforeNavigate events, since when you go to

some folder location, these events are fired, adware takes control,

retrieves the path of a folder, and makes popup.

 

Try to change the AV, or try to remove the registered BHO extension.

But usually, I open regedit and look at the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser

Helper Objects

 

It contains list of GUIDS - these are class ids of COM extensions (in a

simple words, GUID is some long and strange number). Basically, edit the

GUID, for example, my first GUID is: {06849E9F-C8D7-4D59-B87D-784B7D6BE0B3}

 

I just edit it by changing the first elements,

{BLA49E9F-C8D7-4D59-B87D-784B7D6BE0B3}and then you can try to check, whether

the bug disappeared or not. If not, restore the original value of GUID and

play with second GUID.

 

Also, remember, that adwares and other crap tryies to restore it's GUIDs in

BHO registry keys. So, if you delete the entry from registry, it appears

there again within second. This also can be checked.

Also, this tool:

to manage explorer's BHO's.

For non-viral malware...

 

Please download, install and update the following software...

 

Ad-aware SE 2007

http://www.lavasoft.de/

http://www.lavasoftusa.com/

http://www.lavasoft.de/ms/index.htm

 

SpyBot Search and Destroy v1.4

http://security.kolla.de/

http://www.safer-networking.org/microsoft.en.html

 

SuperAntiSpyware

http://www.superantispyware.com/superantis...efreevspro.html

 

After the software is updated, I suggest scanning the system in Safe Mode.

 

I also suggest downloading, installing and updating BHODemon for any Browser Helper

Objects

that may be on the PC.

 

BHODemon

http://www.majorgeeks.com/downloadget.php?...04332b4b8b8442d

 

For viral malware...

 

Download MULTI_AV.EXE from the URL --

http://www.pctipp.ch/downloads/dl/35905.asp

 

To use this utility, perform the following...

Execute; Multi_AV.exe { Note: You must use the default folder C:\AV-CLS }

Choose; Unzip

Choose; Close

 

Execute; C:\AV-CLS\StartMenu.BAT

{ or Double-click on 'Start Menu' in C:\AV-CLS }

 

NOTE: You may have to disable your software FireWall or allow WGET.EXE to go through your

FireWall to allow it to download the needed AV vendor related files.

 

C:\AV-CLS\StartMenu.BAT -- { or Double-click on 'Start Menu' in C:\AV-CLS}

This will bring up the initial menu of choices and should be executed in Normal Mode.

This way all the components can be downloaded from each AV vendor's web site.

The choices are; Sophos, Trend, McAfee, Kaspersky, Exit this menu and Reboot the PC.

 

You can choose to go to each menu item and just download the needed files or you can

download the files and perform a scan in Normal Mode. Once you have downloaded the files

needed for each scanner you want to use, you should reboot the PC into Safe Mode [F8 key

during boot] and re-run the menu again and choose which scanner you want to run in Safe

Mode. It is suggested to run the scanners in both Safe Mode and Normal Mode.

 

When the menu is displayed hitting 'H' or 'h' will bring up a more comprehensive PDF help

file.

 

Additional Instructions:

Please report back your results

Events from Windows Explorer also fires DocumentComplete and BeforeNavigate,

and the path is the path from address bar of Windows Explorer.

I just fixed this problem from my computer a few minutes ago and have

restarted my system, so this is a verified solution. The problem began when I

plugged in a USB drive that has been in contact with a public PC.

 

Treatment:

Run the file 'autoruns' available from the zip file downloadable from

<http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx>. Go to the

second tab ('Logon'), untick the entry 'shell.dll.exe' and then right-click

it to select delete. If warned, give your affirmative to delete. (You may

want to try deleting it straightaway instead of unticking first, I am just

retelling how I did it.)

 

in WINDOWS directory (e.g. C:\WINDOWS), remove the file 'shell.dll.exe'

Note that the file 'shell.dll' - without the .exe extension - should be in

\WINDOWS\SYSTEM32, \WINDOWS\SYSTEM and \WINDOWS\SYSTEM32\dllcache folders

[http://icrontic.com/forum/showpost.php?p=167042&postcount=4].

 

go to Task Manager (i.e. press CTRL-ALT-DEL), go to the Process tab, click

on 'web.exe' and then click the button End Process. Do the same to

'shell.dll.exe' i.e. End Process the 'shell.dll.exe'.

 

then go to My Computer, RIGHT-CLICK (do not double-click!!) on your fixed

drives (e.g. C and D), click EXPLORE. Delete the files 'autorun.inf' and

'web.exe' in each drive. Then delete these files from the Recycle Bin too. At

this stage, left-clicking your fixed drives will still go to the autoplay. It

will prompt that 'web.exe' cannot be found. Right-clicking the drives will,

on the other hand, show a bolded autoplay i.e. the default action for

double-clicking the drive.

 

Restart the system and the above-mentioned autoplay on the fixed drives

won't be there anymore.

I forgot to add that you will need to change the files-view settings in the

windows explorer to see the relevant files.

 

Go to windows explorer (e.g. by going to My Computer), go the menu Tools

(ALT-T), click Folder Options..., choose the tab View, activate Show Hidden

Files And Folders and UNtick the Hide Protected Operating System Files

(Recommended) and, for the latter, click Yes when they ask whether you are

sure. Click OK at the Folder Options dialog box.

 

Do the opposite after you restart your computer doing the steps in the

previous post. I.e. DEactivae Show Hidden Files And Folders and retick the

Hide Protected Operating System Files (Recommended). Click OK at the Folder

Options dialog box.
